What is CVV2? CVC2? Discover® CID?

To help reduce fraud in the card-not-present environment, credit card companies have introduced a card code program. Visa® calls this code Card Verification Value (CVV); MasterCard® calls it Card Validation Code (CVC); Discover® calls it Card ID (CID). The card code is a three- or four- digit security code that is printed on the back of cards. The number typically appears at the end of the signature panel. This helps validate that a genuine card is being used during a transaction, especially in situations like mail orders, telephone orders or Internet orders where the card is not present. All MasterCard cards, both credit and debit, were required to contain CVC2 by January 1, 1997; all Visa cards must contain CVV2 by January 1, 2001. Beginning in October 2003, Discover requires the card code for all Discover transactions.
